Answer:
A) 5.50x + 10y ≤ 800
B) yes
C) no
D) 80 pull buoys and 35 kick boards
Step-by-step explanation:
A) The sum of costs must not exceed the budget:
5.50x +10.00y ≤ 800
__
B) 5.50(0) +10.00(50) = 500 ≤ 800 . . . . . yes, the coach could buy these
__
C) 5.50(125) +10.00(25) = 937.50 > 800 . . . no, they cost too much
__
D) The point (80, 35) is in the solution space. The coach could buy 80 pull buoys and 35 kick boards.
Answer:
190 is the answer of the equation.
Step-by-step explanation:
a(b + c) × 2
Now putting the values of a,b and c.
5(7+12)×2
= 5(19)×2
= 95×2
= 190
Answer:
615.44
Step-by-step explanation:
If diameter = 28, then radius is 14
Area = 3.14 x (14x14) =615.44
We want to find the work done by lifting a book a given distance.
The answer is 200 N*m
We know that the book weighs 100 Newtons and that we lift it a distance of 2 meters.
Remember that the work needed to lift an object of mass M to a height H is:
W = M*g*H
where g is the gravitational acceleration.
Knowing that:
weight = M*g
We can replace the things we know to get the work:
W = 100N*2m = 200 N*m
